Deposition of functional nano-enabled coatings to equipment in a wide variety of industries through a network of service centers
Portfolio company Plakart offers industrial customers services and ready-made solutions for applying multipurpose nanostructured coatings—thermal-barrier, wear-resistant, and corrosion-resistant coatings—through a network of centers. The coatings protect drilling platforms, bridges, steel structures, and associated apparatuses from corrosion. They safeguard stop valves and tubing fittings and drilling and oil and gas production and processing equipment from wear and tear. Robotized equipment and metallurgical labs ensure strict quality control and permit the company to produce coatings with programmed hardness, porosity, and adhesion.
The project uses two of the most popular and promising application technologies in the world—thermal spraying and ion-plasma magnetron sputtering. The new technologies are replacing obsolete and environmentally harmful ones, especially galvanic technology. By combining these technologies, scientists are able to develop coatings with entirely new properties. For example, by depositing nanocoatings, Plakart enabled its client to attain significantly better gas turbine engines performance, higher power, and longer life cycle.

Technologies and Products
The technology of plasma deposition may be used to deposit a broad range of coatings. It is applicable to metals, alloys and heat-resistant ceramics. Specified particles in the form of powder are introduced into a plasma flow whose temperature at the exit of the plasma gun is around 15,000 K. The speed of the flow is around 300 meters per second. Plasma flow is formed by plasma guns or plasma torches consisting of a cone-shaped tungsten cathode and a hollow copper cylindrical anode, with a spray jet set behind the anode. The gas moving between the cathode and the anode is heated by a moving electric arc forming a fiery flow.
Gas-thermal spraying is one of the most rapidly developing methods for depositing coatings. It utilizes the generation of a high-speed gas flow by passing gas through a heat source. Solid-state matter, usually in the form of powder, is introduced into the gas flow melting partially or fully and forming a scaly structure on the base material.
As a heat source, it is possible to use energy from the combustion of a liquid propellant in oxygen (in the High Velocity Oxygen Fuel, or HVOF, method) or energy from an electric arc (in the Air Plasma Spray, or APS, method). Particles in the gas flow obtained by this method have various temperatures and speeds which determine their use in various industries.
